TO ALL WHOM IT MAY CONCERN:

Be it known that I, C'. H. LocKWOoD, ot' llawleyville, in the county of Fairfield, and State of Connecticut, have invented a new and improved Attachment for Sewing-Machines, 'for Sewing Hat-Tips to SideLinings .and I do hereby declare that the 'following is a full, clear, and exact description thereof, which will enable those skilled in the art to make and use the same, reference being had Ato the accompanying drawings, forming part of this specification.

This invention relates to a new and improved attachmcntfor sewing-machines, for the purpose of sewing hat-tips to side-linings; and it consists of a clamp arranged in such a manner as to be capable of being rotated by the feed-mechanism of the machine, and so constructed as to keep the lapped edges of the tip and sidelining in contact, while, by the rotation of the clamp, the lapped edges are fed underneath the needle of the sewing-'machine cach time the former rises above the tip and side-lining.

Hat-tips are most generally of oval form, and in order that the side-lining may be scwcd to the tip at a uniform distance from its edge all around, the clamp is constructed and arranged in such a manner that, while rotating, it is allowed a sliding movement to accomplish that end. In thc accompanying` sheet of drawingsd Figure 1 is avertical central section of my invention, taken in the line x x, g. 2.

Figure 2, a plan or top view of the same.

Similar letters of reference indicate corresponding parts.

A represents a xed npright,which is secured to a bod-piece by means of a screw, B, or other suitable fastening. The upper end of this upright basa hole made horizontally through it, to receive a bar, C, and serre as a guide and bearing for the same.

Thisbar C has a slot, a, made longitudinally in its upper surface, and on one end of said bar there are two rollers, D D, having grooved peripheries, `said rollers having their axes, b, firmly secured in bar C, the rollers turning freely upon them. y

The bar C is formed with a pendent projection, E, through which a horizontal screw, F, passes, said screw having its bearing in the upright A. By turning this screw, the bar C may be adjusted longitudinally. The end of the bar C, which is underneath the rollers D D, is supported by a bracket, G, which is firmly attached to the bed-piece, the bar C being allowed to slide thereon.

II represents an oval plate, the dimensions of which' are equal to the smallest-sized tip designed to be scwed. To the under side of the-plate H thereis attached an oval rim, I, which is concentric with the plate II, and is a short distance below it, on account of being connected therewith by pendent projections c, (sce fig. 1.) The rim I is itted and works between the rollers D D, and the plateH is provided with a central pin, d, which is fitted and works in the slot a in the bar C. This piu el serves as a guide for the oval plate H, and keeps it in place. The feed-mechanism of the sewing-machine, acting upon the material being scwed, rotates the plate H.

The rim I, in consequence of workingl between the rollers/D D, gives the lateral movement to the plate H, the length of said lateral movement being equal to the difference between the major and minor diameters of the oval plate H. In the rotation of the plate H, its edge, which is directly over the rollers D D, is always in one and the same vertical plane, and this edge is in line with the ncedleof the sewing-machine, shown in red in Hg. 1.

.I represents an oval plate, of the same dimensions as the plate H, and having three holes, e, made in it, to receive a corresponding number of pins, f, on plate H. This plate J presses the tip K, shown in red, down upon the plate H, and keeps the tip upon the pins f, causing the former to rotate with plate H, as will`be fully understood by referring to tig. 1.

The two oval plates H J form the clamp, which holds the tip while the side-liningis being sewcd to it. This side-lining, designated by L, is a straight strip of silk, and is hemmed at one edge prior to being sewcd to the tip, and is of sufficient length to extend entirely around the tip. The side-lining is placed or lapped over the edge of the tip, and the sewing-machine being started, the tip and side-lining will be fed along under the needle, and the tip and side-lining scwed together, the stitching or seam being made in oval form, corresponding to the shape of the plate II J, and at an equal distance from said plates all around them.

I would remark that, in consequence of the silk used for hattips being quite thin, a piece of paperiis laid under the tip, in order to give body or strength to the same, and prevent the thread drawing through the fabric under the action of the sewing-machine.

This device muy be made to guide tips of diiferent sizes by adjusting the bar C throughV the medium of the screw F, so as to bring the edge of the plate H J nearer to or further from the needle of the sewing-machine.

A I claim us new, and desire to secure by Letters Pntent- I The oval plate H, provided with the oval concentric rim I, in combination with the bar C, provided with the rollers D D, and the slot a and pin d, or their equivalents, to serve as a guide for the plate H, all constructed and arranged toA operate in the manner substantially as and for the purpose set forth.
